Problems solved by technology

For example, CN107400347A discloses a preparation method of hard hydrophobic PC, but the method is not only complicated in steps, but also involves many intermediate catalytic reactions, and currently only stays in the laboratory stage, and cannot complete industrial production
CN107189656A utilizes long-chain siloxanes to prepare polycarbonate coatings. Although it can achieve superhydrophobic effects, this method is only suitable for coating and cannot be used in the field of injection molding

Abstract

The invention discloses a self-cleaning flame-retardant PC resin and a preparation method thereof. The resin composition is prepared from components in parts by weight as follows: 90-98 parts of PC resin, 0.1-1 part of an antioxidant, 0.2-0.5 parts of a lubricant, 2-10 parts of a surface modification aid, 0.1-0.5 parts of a flame retardant and 0.1-0.8 parts of a UV stabilizer. The preparation method comprises the following steps: uniformly mixing the PC resin, the antioxidant, the lubricant and the flame retardant, feeding into a twin-screw extruder, laterally feeding the surface modificationassistant, and carrying out one-step extrusion molding to obtain the self-cleaning flame-retardant PC resin. The self-cleaning flame-retardant PC is prepared by mixing the raw materials and then carrying out one-step extrusion molding, so that the processing technology is optimized, the processing period is shortened, and the material cost is reduced; and on the premise of keeping high transmittance, the flame-retardant PC material has stable flame retardancy, and can satisfy 1.6 mm V0 flame retardancy, thereby ensuring the safety of the PC product in the use process.

Description

technical field [0001] The invention belongs to the technical field of PC resin, and relates to a self-cleaning flame-retardant PC resin and a preparation method thereof; in particular, to a self-cleaning flame-retardant PC resin with stable flame-retardant performance under the premise of maintaining a high transmittance and its Preparation. Background technique [0002] Self-cleaning, as an important development direction of new functional materials, has been more and more widely used, from architectural decoration materials to various household rain gear such as umbrellas, rain boots to various fabrics, self-cleaning materials can be seen. Self-cleaning materials, as an amphiphobic material that has a certain anti-wetting effect on water and oil, have played a huge role in the fields of waterproof, anti-fingerprint, and anti-fouling. Because of such a strong market demand, many excellent material engineers have made great efforts in the research field of self-cleaning ma...
